Diameter: 6.5 inches when deflated, 18-21 inches when inflated

Each p.ball comes with:

• Adjustable elastic strap
• An extender for universal fit
• A hand pump and needle for easy inflation

Before getting started, make sure the P.volve logo is facing outward. With the p.ball at your ankles, put one foot through the loop and hook the strap around your other ankle. Stand with your feet hip width apart and make sure the p.ball is centered between your ankles. Once the straps are in place, pull the p.ball all the way up your legs. 

Movements can be done both standing or on the p.mat in a variety of exercises.

Does the p.ball fit all sizes?

The p.ball comes in the standard size and a 5.7" extension strap. We also offer additional extensions to fit a variety of body types and different sizes with extenders in 7", 8" and 9.3". 

How do I inflate the p.ball?

Make sure the p.ball is fully inflated before use. The inflation needle is stored in the handle of the pump. Open the cap at the end of the handle to get the inflation needle. Insert the inflation needle on the front of the pump by screwing it on. Dip the inflation needle in water so it does not puncture the valve.

Full inflation size is between 18–21". Use the tape measurer for accuracy. Do not over-inflate the p.ball. Bursting or damage could occur. 

Where is the inflation needle?

• The inflation needle is stored in the handle of the pump
• Open the cap at the end of the handle to find the inflation needle
• Insert the inflation needle on the front of the pump by screwing it on
• Be sure to not over-inflate the p.ball, as bursting or damage could occur
